IntelliSet™

Products carried or stored in a refrigerated compartment require a multitude
of refrigerant unit settings that must be checked, and if required, reset each
time a new product is loaded. The APX control system offers the
settings necessary to meet these requirements. IntelliSet is a feature that
allows pre-selection and naming of the necessary settings for up to 40
different products. The operator may then call up the settings by simply
selecting the assigned IntelliSet name.
For example: a load of apples may require continuous operation at 35°
F (1.7°C) with a defrost every three hours, while a load of cheese may
require the same operation with setpoints ranging from 35°F to 42°F (1.7°C to
5.6°C) and a load of ice cream requires start-stop operation at -22°F (-30°
C) with defrost at 12 hour intervals. The settings required for each product
may be entered into the system and locked so that they cannot be changed,
and they can be given an appropriate name. In the case cheese, the
range of setpoints may be locked, leaving the operator the ability to
change the setpoint within the locked range.
When a load of apples is scheduled for pick-up, the operator simply selects
"APPLES" from the IntelliSet menu. For cheese, select "CHEESE" and the
setpoint reset as required. For ice cream, select "ICE CREAM." With each
selection, the system automatically re-programs the settings to provide the
best temperature control, fuel economy and performance for that
particular product.
An IntelliSet may be pre-programmed as "IntelliSleep" which allows Sleep
mode to be entered by simply changing to that IntelliSet. Range Protect may
be applied to any IntelliSet. Range Protect offers increased fuel savings over
normal Start-Stop Operation for commodities that can use less restrictive
temperature control.
